Hi...

I dont know whether this is strange problem or a simple one. But it is killing me inside.

I have to create a GENERIC sysin card for different input files (with different lrecl)


Below is the SYSIN CARD i am using for single file.

Code:

//TOOLIN   DD *                                                 
  SELECT FROM(IN1) TO(F1) ON(1,11,CH) FIRST                     
  SELECT FROM(IN2) TO(F1) ON(1,11,CH) FIRST                     
  SELECT FROM(F1)  TO(T1) ON(1,11,CH) FIRSTDUP USING(CTL1)     
  SELECT FROM(F1)  TO(T1) ON(1,11,CH) NODUPS USING(CTL2)       
  COPY FROM(IN1) TO(T1) USING(CTL3)                             
  COPY FROM(IN2) TO(T1) USING(CTL4)                             
  SPLICE FROM(T1) TO(OUT1) ON(1,11,CH) WITHALL WITH(1,45) -     
    USING(CTL5)                                                 
/*                                                             
//CTL1CNTL DD *                                                 
  OUTFIL FNAMES=T1,OVERLAY=(45:C'DD')                         
/*                                                             
//CTL2CNTL DD *                                                 
  OUTFIL FNAMES=T1,OVERLAY=(45:C'UU')                           
/*                                                             
//CTL3CNTL DD *                                                 
  OUTFIL FNAMES=T1,OVERLAY=(45:C'11')                           
/*                                                             
//CTL4CNTL DD *                                                 
  OUTFIL FNAMES=T1,OVERLAY=(45:C'22')                           
/*                                                             
//CTL5CNTL DD *                                                 
  OUTFIL FNAMES=OUT1,INCLUDE=(45,2,CH,EQ,C'1U'),BUILD=(1,44)   
  OUTFIL FNAMES=OUT2,INCLUDE=(45,2,CH,EQ,C'2U'),BUILD=(1,11)   
  OUTFIL FNAMES=OUT12,SAVE,BUILD=(1,44)                         
/*   


Can you please help me in this?

Do you need to determine the LRECL automatically, or could you specify it in a record, e.g.

000044

for a run when the LRECL is 44 and

000050

for another run when the LRECL is 50?

Frank,

Yes It should find automatically...

I am planning to write a generic SYSIN which will be accessed by more than 50 JOBs to compare files.

The overlay character should be appended at the end of record without mentioning explictly the 44 or 50 in the sysin.

Thanks,

I'm on vacation today, but I'll see what I can come up with tomorrow.

I started to look at this and came up with another question. You have:

Code:

  OUTFIL FNAMES=OUT1,INCLUDE=(45,2,CH,EQ,C'1U'),BUILD=(1,44)   
  OUTFIL FNAMES=OUT2,INCLUDE=(45,2,CH,EQ,C'2U'),BUILD=(1,11)   


I assume 44 is determined from the LRECL. But how is 11 determined?

Does the m in ON(1,m,CH) have to be determined automatically to or is it always 11?

For the example you showed:

What is the LRECL of the IN1 data set?

What is the LRECL of the IN2 data set?

Maybe the answers to these questions are related

Yes Frank,

44 is determined from the LRECL, 11 is also detemined from the LRECL.

Actually File-1 contains only the account number which is 11 bytes long.
File-2 contains other data including the account number which is 44 bytes long.

We are planning to write a generic card which will be comparing the 11 bytes account number from file-1 to the account number in the file-2 having various LRECL(can be 44, can be 105, can be 80)

Here's a DFSORT/ICETOOL job that will do what you asked for. Just put the input file2 name in step S1 and the input file1 and input file2 names in step S2 where indicated. Step S1 will automatically determine the LRECL of input file2 and create DFSORT Symbols based on it. Step S2 will use those Symbols. Note that I fixed up the first SELECT to create 44 byte records as required.

Code:

//S1    EXEC  PGM=ICETOOL
//TOOLMSG DD SYSOUT=*
//DFSMSG  DD SYSOUT=*
//IN2 DD DSN=...  input file2 (FB/n)
//TEMP1 DD DSN=&&TX,UNIT=SYSDA,SPACE=(TRK,(1,1)),DISP=(,PASS)
//SYM DD DSN=&&S1,UNIT=SYSDA,SPACE=(TRK,(1,1)),DISP=(,PASS)
//TOOLIN   DD    *
COPY FROM(IN2) USING(CTL1)
COPY FROM(TEMP1) USING(CTL2)
/*
//CTL1CNTL DD *
  OPTION STOPAFT=1
  OUTFIL FNAMES=TEMP1,FTOV
/*
//CTL2CNTL DD *
  OUTFIL FNAMES=SYM,VTOF,
    BUILD=(C'SYM1,1,',1,2,BI,SUB,+4,EDIT=(TTTTT),80:X,/,
     C'SYM2,',1,2,BI,SUB,+3,EDIT=(TTTTT),C',2',/,
     C'SYM3,',1,2,BI,SUB,+4,EDIT=(TTTTT),/,
     C'SYM4,1,',1,2,BI,SUB,+3,EDIT=(TTTTT))
/*

//IN1 DD DSN=...  input file1 (FB/11)
//IN2 DD DSN=...  input file2 (FB/n)
//F1 DD DSN=&&F1,UNIT=SYSDA,SPACE=(CYL,(5,5)),DISP=(MOD,PASS)
//T1 DD DSN=&&T1,UNIT=SYSDA,SPACE=(CYL,(5,5)),DISP=(MOD,PASS)
//OUT1 DD DSN=...  output file1 (FB/n)
